Week 1 is the first active Sleepgenic Weekly Report after the baseline period. The purpose of this report is to compare the first weekly sleep pattern against the Week 0 baseline and identify whether the body is moving toward recovery, strain, adaptation, or instability.
Across Week 1, the average Overall Score was 60.2, compared with the baseline median of 67.5, a decline of 7.3 points. The Quality Score averaged 69.5, down from 74.0, while the Duration Score averaged 66.5, down from 72.0. The largest scoring decline came from Recovery Score, which averaged 62.0, compared with the baseline median of 75.5, a drop of 13.5 points.
At the score layer, Week 1 was clearly below baseline.
But the physiological layer tells a more nuanced story. Deep sleep averaged 1.46 hours, above the baseline median of 1.25 hours. HRV averaged 37.2 ms, also above the baseline median of 35.0 ms. Resting heart rate averaged 63.2 bpm, lower than the baseline median of 65.0 bpm. Restless moments averaged 40.7, below the baseline level of 44.0.
These are not collapse signals. They suggest that even though the weekly scores declined, the body maintained or improved several important recovery markers.
The main negative signal was stress. Sleep Stress averaged 20.4, compared with the baseline median of 17.2, an increase of 3.2 points. Total sleep also averaged 5.75 hours, slightly below the baseline median of 5.99 hours. REM sleep was effectively flat, averaging 0.80 hours compared with the baseline of 0.81 hours, but the week included several nights where REM structure was weak or incomplete.
The week also showed strong variability by stimulus type. The lowest Overall Score came after the run day on 4/23/2026, with a score of 41, Recovery Score of 29, Duration Score of 29, and total sleep of only 3.60 hours. The summit-related night on 4/19/2026 also scored poorly despite long sleep duration, showing an Overall Score of 49 with 8.42 hours of sleep. That night was long, but not restorative.
The strongest recovery night came on 4/20/2026, after the summit, with an Overall Score of 82, Recovery Score of 87, Duration Score of 89, HRV of 44 ms, resting heart rate of 61 bpm, and Sleep Stress of 13.4. This was the clearest positive adaptation signal of the week.
The interpretation is that Week 1 was not simply a bad sleep week. It was a mixed adaptation week. The score layer declined because sleep duration, REM structure, and sleep stress were inconsistent. But the underlying physiology showed resilience through improved deep sleep, higher HRV, lower resting heart rate, and fewer restless moments.
Sleepgenic classifies Week 1 as adaptation pressure after load. The body absorbed significant stimulus, showed signs of strain, but did not break down. The key watch item going forward is whether future weeks convert this pressure into better sleep consistency, lower sleep stress, and stronger REM recovery.
